This past week I attended the Madison PMO Managers Forum where two members showed their live project SharePoint sites. It was great to see a behind the scenes look at others SharePoint sites. One member of the group vented his frustration about moving existing files into a document library within SharePoint. I too had issues with this since it seems you can only upload 1 file at a time, but there is a solution to this!
Open your file library and click on Actions, select "open with Windows Explorer" and like magic you have a file browser that looks like the one you are use to using in Windows. Now you can create folders or drag and drop (or copy and paste) files from the old location to the new location.
The advantages to using the document library in SharePoint 2007 are:
1. You can turn on versioning; so every time you update a document the old one is still accessible.
2. Easy editable permissions. No more asking IS to lock down folders when you can do it yourself!
3. It treats it as a database that you can add columns of data to it, like a description (that is searchable).
4. Document checkout; you can have a team work on a document, by having one person “checkout” the document to work on it.
5. Email notification if someone adds or edits a document.
